[ Upstream commit e0dd27ad8af00f147ac3c9de88e0687986afc3ea ]
Handle the trace interrupt in the hardirq context, make sure the irq
core won't threaded it by declaring IRQF_NO_THREAD and userspace won't
balance it by declaring IRQF_NOBALANCING. Otherwise we may violate the
synchronization requirements of the perf core, referenced to the
change of arm-ccn PMU
commit 0811ef7e2f54 ("bus: arm-ccn: fix PMU interrupt flags").
In the interrupt handler we mainly doing 2 things:
- Copy the data from the local DMA buffer to the AUX buffer
- Commit the data in the AUX buffer

for non HDMI hdev do not register the HDMI dais.

[ Upstream commit c13c823a78b77ea0e5f1f73112d910e259911101 ]
The rk3399-gru PCI node addresses are wrong.
In rk3399-gru-scarlet, the bus number in the address should be 0. This is
because bus number assignment is dynamic and not known up front. For FDT,
the bus number is simply ignored.
In rk3399-gru-chromebook, the addresses are simply invalid. The first
"reg" entry must be the configuration space for the device. The entry
should be all 0s except for device/slot and function numbers. The existing
64-bit memory space (0x83000000) entries are not valid because they must
have the BAR address in the lower byte of the first cell.
Warnings for these are enabled by adding the missing 'device_type = "pci"'
for the root port node.

[WHY]
Some eDP panels's ext caps don't write initial value cause the value of
dpcd_addr(0x317) is random. It means that sometimes the eDP will
clarify it is OLED, miniLED...etc cause the backlight control interface
is incorrect.
[HOW]
Add a new panel patch to remove sink ext caps(HDR,OLED...etc)

[ Upstream commit 8d1b7809684c688005706125b804e1f9792d2b1b ]
Fix a wrong error checking in exynos_drm_dma.c module.
In the exynos_drm_register_dma function, both arm_iommu_create_mapping()
and iommu_get_domain_for_dev() functions are expected to return NULL as
an error.
However, the error checking is performed using the statement
if(IS_ERR(mapping)), which doesn't provide a suitable error value.
So check if 'mapping' is NULL, and if it is, return -ENODEV.
This issue[1] was reported by Dan.

[ Upstream commit d6c5f06e46a836e6a70c7cfd95bb38a67d9252ec ]
Currently, we store syscall nr in pt_regs::regs[11] and syscall execve()
accidentally overrides it during its execution:
sys_execve()
-> do_execve()
-> do_execveat_common()
-> bprm_execve()
-> exec_binprm()
-> search_binary_handler()
-> load_elf_binary()
-> ELF_PLAT_INIT()
ELF_PLAT_INIT() reset regs[11] to 0, so in syscall_exit_to_user_mode()
we later get a wrong syscall nr. This breaks tools like execsnoop since
it relies on execve() tracepoints.
Skip pt_regs::regs[11] reset in ELF_PLAT_INIT() to fix the issue.

[ Upstream commit 37e6fd0cebf0b9f71afb38fd95b10408799d1f0b ]
Bit 6 of INPPGA (INPPGAMUTE) does not control the Aux path, it controls
the input PGA path, as can been seen from Figure 8 Input Boost Stage in
the datasheet. Update the naming of things in the driver to match this
and update the routing to also reflect this.

skl_platform_register() uses krealloc. When krealloc is fail,
then previous memory is not freed. The leak is also when soc

The controller state is typically written by another CPU, so reading it
should ensure no optimizations are taken. This is a repeated pattern in
the driver, so start with adding a convenience function that returns the
controller state with READ_ONCE().

Do we still want this hack on older kernels that don't support GSP?

[ Upstream commit 16b55b1f2269962fb6b5154b8bf43f37c9a96637 ]
When an EEH error is encountered by a PCI adapter, the EEH driver
modifies the PCI channel's state as shown below:
enum {
/* I/O channel is in normal state */
pci_channel_io_normal = (__force pci_channel_state_t) 1,
/* I/O to channel is blocked */
pci_channel_io_frozen = (__force pci_channel_state_t) 2,
/* PCI card is dead */
pci_channel_io_perm_failure = (__force pci_channel_state_t) 3,
};
If the same EEH error then causes the tg3 driver's transmit timeout
logic to execute, the tg3_tx_timeout() function schedules a reset
task via tg3_reset_task_schedule(), which may cause a race condition
between the tg3 and EEH driver as both attempt to recover the HW via
a reset action.
EEH driver gets error event
--> eeh_set_channel_state()
and set device to one of
error state above scheduler: tg3_reset_task() get
returned error from tg3_init_hw()
--> dev_close() shuts down the interface
tg3_io_slot_reset() and
tg3_io_resume() fail to
reset/resume the device
To resolve this issue, we avoid the race condition by checking the PCI
channel state in the tg3_reset_task() function and skip the tg3 driver
initiated reset when the PCI channel is not in the normal state. (The
driver has no access to tg3 device registers at this point and cannot
even complete the reset task successfully without external assistance.)
We'll leave the reset procedure to be managed by the EEH driver which
calls the tg3_io_error_detected(), tg3_io_slot_reset() and
tg3_io_resume() functions as appropriate.
Adding the same checking in tg3_dump_state() to avoid dumping all
device registers when the PCI channel is not in the normal state.
